Combine the starter, flour, buttermilk, eggs, melted butter and sea salt.
Mix well, cover and allow to sit on the kitchen counter for at least 8 hours or overnight if possible to ferment.
After allowing your batter to ferment add the bone broth and your favorite mix ins.
My favorite is 1 tsp garlic powder, 1 tsp pepper, 1 cup shredded cheddar, 1 cup chopped ham, turkey or bacon, 1 tablespoon dry or fresh chives.
Butter your waffle iron generously and cook according to your waffle iron instructions.
Serve nice and hot with a fried egg on top !
